(1) 3 ? ? from Willowmore {Dr. H. Brauns). 



Tlie T-shaped median ridge of the vulva is normally white 

 in colour, but occasional! jit is more or less lightly browned ; 

 the posterior part, too, is sometimes broad behind and 

 parallel-sided, instead of being wedge-shaped. The carapace 

 of the ? does not exceed 2* mm. in length in the largest 

 specimen, that of the largest (S being slightly less. The 

 anterior lateral eyes are their own diameter or less from the 

 anterior margin of the carapace. The spots on the abdomen 

 are occasionally absent. In some S S > notably those from 

 Matjesfontein, the two proximal teeth of the superior margin 

 of the chelicera are less completely fused and separately 

 distinguishable. 



The species is closely allied to D. morosus (O. P. Cambr.) 

 from Palestine, the figure of whose palp, given by Cambridge 

 (P. Z. S. 1872, pi. XV. fig. 9), almost exactly resembles the 

 palp of D. lophognathus, sp. n. In D. morosus, however, the 

 eyes of the posterior row are said to be equidistant from each 

 other. D. omissus (O. P. Cambr.), from Palestine, has a 

 very similar vulva (P. Z. S. 1872, pi. xv. fig. 17). 



2. Drassodes tessellalus, sp. n. 

 (PI. XIII. figs. 7 & 8.) 



Specimens. — (a) 17 c? (^ and 45 ? ? , besides a pair in 

 ci'puld ; also 6 ? ? with variety of the vulva; all collected 

 at Hanover by Mr. S. C. Cronwright Schreiner in 1901. 



Very closely allied to D. lophognathus, sp. n., but larger, 

 and diflfering principally in the form of the proximal tooth on 

 the inner side of the large sigmoid process of the palpal 

 organ, this tooth (which is hidden under the tarsus) forming 

 a broad truncated lobe and much broader than the distal 

 tooth (PI. XIII. fig. 8). 



Colour. — ('arapace often rufescent, the head and chelicera 

 red, the legs yellowish or reddish yellow, the abdomen 

 speckled as in lophognathus. 



Posterior median eyes slightly more than an eye's diameter 

 from the laterals, and the anterior lateral eyes generally 

 slightly more than a diameter from the anterior margin of 

 the carapace. 



Chelicera oi ^ S with the two proximal teeth on superior 

 inner margin fused to a keel or more or less separate. 



Vulva of ? ? normally resembling that of lophognathus, 

 the median T-shaped ridge being generally whitish ; often, 

 however, this ridge is browned or reddened, and in the
